I may have more information for the children of John Joseph Simpson & Hannah Self for you if you do not already have found more info since February of 2010. The 1870 census for the Sabine Parish actually lists the children.
The information that I am trying to find is John Joseph's parents or anything. John Joseph and Hannah were married in 1846 but by the 1870 census John Joseph is not listed. The youngest child, Josephine was born 1864. So, what happened to John Joseph Simpson between 1864 & 1870? Civil war was 1861 to 1865 so could he have fought there? I would like to collaborate. -- Howard Simpson
